LA PAZ (Reuters) - A scientific expedition high in the Bolivian Andes revealed 20 species new to science, including "lilliputian frog" plus four rediscovered species including the "devil-eyed frog" previously thought to be extinct, Conservation International said.

The expedition was led by the environmental group and the government of capital city La Paz. It included 17 scientists who went to the Chawi Grande, a locality belonging to the Huaylipaya indigenous community near La Paz.
